1. Intshayelelo: Imingeni Ekhethekileyo YeeSidibi Zemilambo Ezincinci NeziPhakathi
Kwiminyaka eli-15 ndiyila uthungelwano lokujonga imeko-bume, ndifumanise ukuba imisele yomlambo emincinci nephakathi iphakathi kwezona ndawo zinzima ukuzilawula. Ezi nkqubo zidume ngokuguquguquka; ngokungafaniyo nemilambo emikhulu ephendula kancinci xa imvula ina, imisele emincinci inokutshintsha ukusuka kwimeko ezinzileyo ukuya kwisikhukula esisongela ubomi kwimizuzu embalwa.
Ukulinganisa okusekelwe ekuchukumiseni ngokwesiko—ukuxhomekeka kwiitransducers zoxinzelelo olungaphantsi komhlaba okanye iirotor zoomatshini—akufanelanga ngokupheleleyo ezi meko. Ngexesha lesikhukula, ezi zitya zibonisa ukuhamba okukhawulezayo okukhawulezayo kwaye zithwala ubuninzi benkunkuma edadayo, imithi, kunye nenkunkuma. Ezi meko zihlala zikhokelela ekushukumeni kwenzwa, ukuvaleka, okanye ukutshatyalaliswa ngokupheleleyo kwezixhobo ezingaphantsi komhlaba kanye xa idatha ibaluleke kakhulu. Itekhnoloji yeradar engathintaniyo, ngakumbi uthotho lwe-RD-600, iye yavela njengomgangatho wobungcali. Ngokulinganisa ukusuka ngaphezulu komphezulu wamanzi, sisusa umngcipheko womzimba kwizixhobo kwaye siqinisekisa ukuthembeka kwesilumkiso "senethiwekhi yokhuseleko" kwangethuba.
2. Isisombululo Esiphambili: Umlinganiselo Wokuhamba Kweradar Engadibaniyo
I-RD-600 radar flowmeter isebenzisa i-economicI-Planar Microstrip Array AntennaukuqeshaCW + PCRItekhnoloji (i-Continuous Wave kunye ne-Pulse Coherent Radar). Le ndlela imbini ivumela ukulinganiswa ngaxeshanye, ngokuchanekileyo okuphezulu kwesantya somphezulu kunye nenqanaba lamanzi ngaphandle kokutshintsha iimeko zomda we-hydraulic womlambo okanye umjelo.
Indlela kunye neMigaqo
- Umlinganiselo weVelocity:Le nkqubo isebenzisa umgaqo weDoppler ukubamba isantya somphezulu. Isignali ye-24GHz ikhutshwa (amandla aqhelekileyo e-100mW) kwi-engile yokukhupha amaza erediyo ye-12°. Utshintsho lwefrikhwensi yesignali yokubuya lubonelela ngokufundwa kwesantya sexesha langempela.
- Indlela yeVelocity-Area:Ukulinganisa isantya somphezulu linyathelo lokuqala kuphela. Ukubonelela ngesantya sokwenyani sokuhamba kwamanzi, inkqubo idibanisa idatha yayo yamanzi ukuze ibale indawo enqamlezileyo. I-RD-600 icwangciswe kwangaphambili ngeiifomula zovavanyo lokusasazwa kwesantyakwiijiyometri ezahlukeneyo zetshaneli, kuquka iindawo ezijikelezayo, ezixande, kunye nezetrapezoidal. Oku kuvumela imodeli yangaphakathi ye-hydraulic ukuba iguqule isantya somphezulu sibe sisantya esiphakathi esibaliweyo secandelo lonke.
- Iimpawu Eziqinisiweyo:Ngokwembono yobunjineli, ii-RD-600ukuqatshelwa ngokuzenzekelayo kwendlela yokuhamba kwamanzikwayeukulungiswa kwe-engile ethe nkqo eyakhelwe ngaphakathiazinamsebenzi. Ezi mpawu zinciphisa iimpazamo eziqhelekileyo zokufakela kwiindawo ezirhabaxa, ziqinisekisa ukuthembeka kwedatha nokuba iimeko zokufakela azilunganga kangako.
Iingenelo zeNdlela yokungaqhagamshelani:
- Ukhuseleko lweZiseko zoPhuhliso:Ixhonywe phezu kwamanzi, le sensor ayichaphazeleki zizinto ezibangelwa zizikhukula kwaye ichaphazeleka ngokukhawuleza kakhulu yi-"flood peak".
- Ukunyaniseka kweHydraulic:Akukho thintelo lubekwe emanzini, nto leyo ethintela naluphi na utshintsho kwiimpawu zokuhamba kwamanzi okanye ukuqokelelwa kwenkunkuma.
- Ukusebenza kakuhle:Inkqubo isebenza ngesantya esiphantsi kakhulu3.5~4.35VDCuluhlu. Kwizikhululo ezikude, ezisebenzisa amandla elanga endihlala ndiziyila, olu setyenziso luphantsi lwamandla luyinto ebalulekileyo ekuthembekeni imini nobusuku.
3. Izinto ezibalulekileyo zeNkqubo yesilumkiso seMeteorological Hydro-Meteorological
Inkqubo yokulumkisa kwangethuba eqinileyo ayisiyonto inye nje kuphela; yi-hardware suite ehambelanayo eyenzelwe ukubamba ulwalamano "lwe-Rainfall-Runoff" (降雨-径流).
- Inzwa yesantya seRadar:Isebenza kwi-24GHz, le sensor ibamba isantya se-flood peak (洪峰流速) ngaphakathi komgama we-0.03 ukuya kwi-20m/s. Ukuchaneka kwayo kwe-±0.01m/s kunye ne-±1%FS kuqinisekisa ukuba notshintsho oluncinci kakhulu ekuhambeni kwamanzi luyarekhodwa.
- Inzwa yeNqanaba laManzi yeRadar:Isebenzisa i-frequency ye-60GHz ene-engile ye-antenna encinci ye-8° (amandla e-10mW), le sensor inika uluhlu lokulinganisa lweemitha ezingama-40 oluchanekileyo lwe-±2mm. Eli nqanaba lokuchaneka lisisiseko salo naliphi na isilumkiso sezikhukula zesantya.
- Izinzwa zemvula (Ibhakethi yokuncamathelisa):Sisebenzisa ibhakethi yedijithali yentsimbi engagqwaliyo ene-caliber engama-210mm. Uyilo lwayo olucwangcisiweyo lwe-3D lwenzelwe ngokukodwa ukuzicoca kunye nokumelana nothuli, ikhupha idatha ngeprotocol eqhelekileyo yeMODBUS-RTU.
- Uhlalutyo Lokuqikelela:Ngokudibanisa idatha yemvula kunye nokuhamba kwexesha langempela, singahlalutya ubudlelwane phakathi kwemvula kunye nokuphuma kwamanzi. Oku kubandakanya ukubala "ixesha lokulibaziseka" phakathi kwesiganeko semvula kunye nokufika kwencopho yezikhukula. Ngokuqonda ukufuma kwangaphambili kunye nobukhulu bemvula, inkqubo iqikelela imida ebalulekileyo, inika abasemagunyeni ithuba elikhulu lokuphuma kunye nokuphendula ngokukhawuleza.
4. Ukwandisa uMda: Umthwalo weNdalo kunye nokuHlanganisa uNgcoliseko
Ulawulo lwemilambo lwanamhlanje luye lwaphucuka ngaphaya kokuthintela iintlekele; ngoku sigxile ngokulinganayo kukhuseleko lwendalo. Ngokudibanisa iiMulti-parameter Water Quality Sensors, sinokujonga impilo yeekhemikhali yesitya kunye nokuhamba kwaso ngokwasemzimbeni.
Iiparameter zoMgangatho wamanzi oPhezulu

I-"Flux" Equation kunye nokuvumelanisaIxabiso lokwenyani lolu dibaniso kukubalwa kwePollutant Flux:
Izinga lokuhamba (ukusuka kwiRadar) × Uxinzelelo (ukusuka kwiSensor yoMgangatho waManzi) = Ukungcola okuNgcolisayo
Ii-4G RTU edibeneyoIsebenza njengengqondo yenkqubo, iqinisekisa ukuba ixesha ledatha yokuhamba lihambelana ngokugqibeleleyo nedatha yoxinaniso. Olu lungelelwaniso lwexesha luvumela ii-ofisi zokusingqongileyo ukubala ubunzima obupheleleyo bento engcolisayo ehamba kwicandelo elinqamlezileyo, nto leyo ebalulekileyo ekuvavanyeni umthwalo wendalo kunye nokulandelela imithombo yokukhupha ngokungekho mthethweni ngokuchanekileyo kwezibalo.
5. Iinkcukacha zobugcisa kunye nokuqina kwenkqubo
Ukuze imelane nobunzima bokusasazwa kwentsimi, le nkqubo yenzelwe ukhuseleko oluphezulu kwimizi-mveliso:
- Ukumelana nokusingqongileyo:Ukusebenza okugcweleyo kugcinwa iiyure ezingama-24 ngosuku, iintsuku ezisixhenxe ngeveki, kuquka nemvula enkulu, ukusuka kwi -30°C ukuya kwi +80°C.
- Ukuqina Komzimba:Izixhobo zineUvavanyo lokukhusela lwe-IP68kunye neempawuUkhuseleko lombane lwe-6KV, ikhusela izixhobo zombane ezibuthathaka kwiingxaki zombane ezixhaphakileyo ngexesha leenkqwithela ezinkulu.
- Uqhagamshelo:Idatha idluliselwa nge-RS485 (MODBUS-RTU), RS232, okanye i-4~20mA. I-4G RTU edibeneyo ekhethiweyo ibonelela ngesisombululo se-telemetry esingenamthungo kwiindawo ezikude zomlambo apho iziseko zophuhliso ezineentambo zingekhoyo.
6. Isiphelo: Indlela Eqhutywa Yidatha Yolawulo Lomlambo
Ukudibanisa umlinganiselo wokuhamba kweradar engadibaniyo kunye nokubona imvula kunye nomgangatho wamanzi kudala "umnatha wokhuseleko" opheleleyo kwixesha lanamhlanje. Ngokutshintsha izinzwa zoqhagamshelwano ezisengozini ngetekhnoloji yeradar yeCW + PCR eqinileyo, sisusa iindawo ezingabonakaliyo ezenzeka rhoqo ngexesha lezona zigaba ziyingozi kakhulu zomkhukula. Le ndlela iqhutywa yidatha inika ulwazi oluchanekileyo olufunekayo ekunciphiseni iintlekele ezingxamisekileyo kunye nokulawula ixesha elide izixhobo zethu zamanzi ezibalulekileyo kwindalo.
